Applying hair treatment with a hair iron

ABSTRACT

A hair iron has two hingedly connected arms between which hair may be clamped and heated. A heating element is included on one or both arms, regulated by a temperature controller. A compartment is formed in one or both arms to hold a capsule for containing a fluid, and a connector, which includes liquid passing ports and a gas passing ports, the connector forming a coupling between the capsule and a pump and dispensing outlets within the arm. As the pump is pressed, gas passes through the connector into the capsule, creating pressure to force out liquid. The liquid passes through the connector and arm to exit at dispensing outlets located near the heaters. The fluid may be converted to steam by the heating elements.

Referring now to FIGS. 1-2, in an embodiment of the disclosure, a disposable fluid capsule, cartridge, or container 200 is removably connected within a hair iron 100. Application of a gel or fluid 400, such as but not limited to water and or a hair care product, from capsule 200, is facilitated by a removable pump cap or pump connector 300. Both capsule 200 and connector 300 are advantageously at least partially internally positionable, when in use, within hair iron 100, in a cartridge compartment 150, and may be covered from the environment by a detachable cover 500. In an additional embodiment in accordance with the disclosure, multiple connectors 300 connectable with multiple capsules 200, housed together within compartment 150, or other compartments within hair iron 100, thereby permitting a user to simultaneously and selectively mix multiple types of fluids 400, for application to the hair of a user, during use of iron 100.

In reference now to FIGS. 1-2 and 6-11, an embodiment of a hair iron 100 includes an elongated first or upper arm member 102, an elongated second or lower arm member 104, and at least one heating element 106, affixed to at least one or both arms 102, 104 on the inner or heating side of the arm. The heating elements may be resiliently mounted with the use of one or more elastomeric pads 224 or other biasing element, to protect elements 106, 106B, 106C from vibration, and to better conform to a hair passed through iron 100. The arms 102, 104 are connected at a hinge 108, thereby permitting pivotal rotation about a hinge axis between an open position and a closed position, the rotation resulting in the arms closing together on, or clamping hair inserted between, arms 102, 104. In one embodiment, a spring 120 is provided between arms 102, 104 in order to return the arms 102, 104 to an open position during a resting state, or to reposition the iron, the spring in an embodiment providing resistance to the closing of the arms 102, 104. Spring 120 can be housed within a spring compartment 122. In one embodiment, spring 120 is a helical spring, housed adjacent to hinge 108. Other biasing methods may be used, including a resilient block, or a flat spring. A locking mechanism (not illustrated) may be further provided either along the arms 102, 104 or within proximity to the hinge in order to restrain the arms in a closed position, which is advantageous for storing the hair iron 100 when not in use, or holding arms 102, 140 closed for a limited time during use. Alternatively, the locking mechanism may keep the arms in an open position so as not to unnecessarily engage the heating elements 106 when the iron 100 is not in use.

Power is provided to the iron 100 by means of a cord 110, connectable to a source of electricity; however, it should be understood that wireless power known or yet to be developed, including batteries, may be used to power the iron 100, in an alternative embodiment in accordance with the disclosure. Cord 110 may be advantageously rotatable at a cord connection point 128, thereby permitting cord 110 to remain rotationally stationary when iron 100 is rotated, or vice-versa when cord 110 is rotated and iron 100 is held stationary. This feature advantageously keeps cord 110 from twisting as iron 100 is manipulated through the hair of a user or subject, thereby reducing the mechanical wear on cord 110 and, consequently, improving the durability of the invention.

As may be seen in FIG. 12, in one embodiment, a rotatable electrical connector 170 includes a first pair of mating electrically conductive rings 172, 174, ring 174 resiliently expandable to engage the other with pressure, and a second pair of similarly configured relatively larger rings 176, 178, with ring 178 being resiliently expandable. In the illustration, the rings are disassembled, to clarify the various parts, and are assembled by inserting ring set 172, 176 within ring set 174, 178, along the direction of arrow “E”. In an assembled electrical connection between the smaller rings 172, 174, the non-resilient ring 172 has been passed through the larger resilient ring 178 to electrically engage the smaller resilient ring 174. Similarly, larger non-resilient ring 176 is inserted within resilient ring 178. Rings 172 and 176 are non-conductively mutually connected, and rings 174 and 178 are similarly non-conductively mutually connected. One of connected set 172, 176 or 174, 178 are connected by wires 180 to a line source of electricity, and the other set is connected by wires 182 to an electrical load, or electrical components of iron 100. Set 172, 176 may rotate within set 174, 178 while conducting electricity. A stop (not shown) may be formed between the sets 172, 176 and 174, 178, so that a maximum number of revolutions in a single direction, for example less than one, is maintained between sets, preventing excess stress on the components of the connection. It should further be understood that rings 174 and 178 may be the same or a different size, and rings 172 and 176 may be the same or a different size.

Heating elements 106 may be heated from an ambient temperature, for example the environment temperature, to an elevated temperature selected, for styling hair. Elevated temperatures can range, for example, from 140 degrees to 450 degrees Fahrenheit, when the iron 100 is activated, in accordance with the disclosure, but it should be appreciated that this temperature range may vary depending on a variety of factors, including the application of hair iron 100, a duration of clamping of arms 102, 104, materials used to manufacture the iron 100, the amount of power supplied to iron 100, and any hair care products, gels, or liquids that may be used in conjunction with the hair iron 100.

Hair iron 100 may be electrically activated by a power switch 112, thereby providing electricity to additional portions of iron 100, including heating elements 106. A temperature control 114 is advantageously provided, for example upon cord 110 or an an exterior surface of iron 100, permitting a user to adjust the desired temperature of heating elements 106 within an optimal temperature within a range of possible temperature settings. In the embodiment illustrated, power switch 112 is positioned upon arm 104, and temperature control 114 is a wheel or dial positioned additionally position upon arm 104, for example upon a side portion of arm 104, easily accessed by a thumb of a user. Dial 114 may advantageously include temperature indicia on the dial, corresponding to the temperature, or range setting, of the heating elements 106 when the iron 100 is powered on, and the present position of dial 114.

When the power switch is activated, and cord 110 is connected to an electrical source, a power indicator or light 116, illustrated in the embodiment shown as being provided on the inner side of lower arm 104, will illuminate. In an advantageous embodiment, indicator 116 is a light-emitting diode (LED) light source capable of emitting a plurality of colors corresponding to the state of the iron 100. For example, the light may be green when the iron is powered and red when the heating elements 106 have reached a certain temperature.

Heating elements 106 may include any of a variety of heat conducting materials, including for example, metal or ceramics. In an embodiment of the disclosure, heating elements 106 are advantageously covered with metal plating, for example stainless steel or titanium, which provides a low friction, smooth surface when contacting human hair, thereby producing superior hair styling results to other known plating materials, such as ceramics, which provide an irregular surface thereby increasing the snagging and damaging of hair during use. Titanium is further advantageous for its superior heat conducting properties, thereby permitting both higher temperatures and improved thermostatic control. Electrical heating elements 106, 106B, 106C may be sealed with heat conducting adhesive tape, and may be insulated from other components of iron 100, for example plastic components, by a heat insulative material, for example mica.

As illustrated in FIGS. 1-5, disposed within elongated first arm or member 102 is a cartridge compartment 150 for receiving at least one removable capsule 200 and connector 300. The compartment 150 is covered from the environment by a detachable cover 500 formed to tightly fit over compartment 150 while advantageously maintaining a smooth surface along the outer side of the arm member. In the embodiment shown in FIGS. 1 and 2, a lip 510 is provided on cover 500 and is engagable with a slot 152 provided in compartment 400, thereby guiding cover 500 to first arm 102. Cover 500 is then securable by a clip 154 disposed within arm 102 and connectable with a tab 512 positioned on the underside or arm facing side of cover 500. Tab 512 is secured to clip 154 by a user pressing the two components together, thereby snapping cover 500 into place. Cover 500 may be removed by a user forcing or pressuring the cover upwards, thereby releasing tab 512 from clip 154, as shown in FIG. 2B. In another embodiment, tab 512 and clip 154 are angled so as to facilitate the removal of cover 500 by a user sliding or gliding tab 512 away from clip 154. In an additional embodiment, cover 500 is releasable by means of actuating a switch (not illustrated) thereby releasing tab 512 from clip 154. It should be understood, however, that additional known or yet to be developed means for securing a cover to a compartment may be used to secure cover 500 over compartment 150.

Advantageously, cover 500 forms a tight seal over compartment 150, or compartment 150 is insulated from an interior of iron 100, so as to protect the internal mechanical and electrical components of iron 100 from being damaged from the environment, particularly from fluids or liquids which may be prevalent in an environment that iron 100 may be commonly used, such as a bathroom or salon, or from liquids released inadvertently from capsule 200. In accordance with the disclosure, cover 500 is formed so as to securely fit over compartment 400 and within arm 102, maintaining a smooth, contiguous surface between arm 102 and cover 500 when the cover is secured, which advantageously assists gripping of iron 100 by a user. It should be understood that additional gripping elements or surfaces may be provided, for instance along arms 102, 104 or along cover 500.

It is advantageous to protect capsule 200 and connector 300 from the environment of use, because this permits components houseable within compartment 150 to be composed of a greater variety of materials, or of different durability of construction, than an outer housing of iron 100. Temperature sensitive materials, for example, which could not be utilized in constructing the capsule 200 or connector 300, if either element was positioned within a close proximity to heating element 106, can be used if protected in this manner. This also holds true, as another example, for moisture sensitive materials. Thus, the enclosed pump system design of the instant disclosure permits a wider range of materials to be used.

Referring to FIGS. 3-5, a capsule 200 and pump connector 300 are provided, in accordance with the disclosure, for administering hair care product, gel, or another fluid 400 through the iron 100 to hair of a user or subject. Capsule 200 is comprised of a hollow shell or body 210, the interior of which defines, at least in part, a reservoir 212 for holding the fluid 400 (not illustrated), and a capsule opening 214 which may internally receive a dispensing tube 310 associated with the connector 300, through opening 214. In the embodiment illustrated, opening 214 has a smaller interior diameter than the reservoir 212, however opening 214 may have the same, or larger interior diameter than the reservoir 212. Additionally, opening 214 and reservoir 212 are illustrated as being cylindrical with a circular cross section, however other shapes or designs may be utilized.

Capsule 200 may advantageously have a length between about 1 inch to 6 inches, and in one embodiment between about 1.5 inches and about 3 inches. Additionally, capsule 200 and connector 300 may have a width between about 0.4 inches and 2 inches, and in one embodiment, between about 0.6 inches and 1 inch. Furthermore, capsule 200 and connector 300 may have a height between about 0.1 inches and about 0.4 inches, and in one embodiment, between about 0.2 inches and about 0.4 inches. It is advantageous that embodiments of capsule 200 and connector 300 are sufficiently small to limit manufacturing costs, while improving portability and adaptability to use with different sized irons 100. Capsules 200 within these dimensions are advantageously light weight, weighing at or less than 0.01 lbs, and are capable of holding at least several milliliters of fluid 400. For example, a capsule advantageously having a length of about 2.2 inches, a width about 0.8 inches, and a height of about 0.25 inches weighs about 0.0013 lbs and has a reservoir 212 capacity of about 0.20 oz (6 mL).

It should be understood that the sizes and capacities of capsule and cap can be much smaller or much larger than described herein. As non-limiting examples, capsule 200 and cap 200 could be half the afore-described size, or twice as large, the size best determined by the amount of treatment desired to be applied, for example, in a single session, balancing weight and cost. Further, it may be desirable that once opened, a capsule 200 is completely emptied, and therefore a quantity could be wasted if capsule 200 is excessively large.

In an embodiment of the disclosure, a locking means for securing pump connector 300 to capsule 200 is externally provided on opening 214, wherein the locking means advantageously comprises an engagement surface 220, at least one locking gap 218, and at least one upper edge or thread 216. Disposed on the capsule receiving end of pump connector 300 is at least one locking finger 320 for engaging the upper edge 216. Pump connector 300 is thereby releasably securable to capsule 200 by inserting or sliding finger 320 past engagement surface 220 and through locking gap 218, then rotating capsule 200 thereby sliding finger 320 under edge 216 resulting in edge 216 restraining finger 320 from sliding away. This embodiment of the locking means advantageously permits pump connector 300 to be releasably secured to container 200 by easily sliding the capsule receiving end of pump connector 300 over or past opening 214, thereby engaging fingers 320 with gaps 218, and rotating capsule 200 circumferentially about opening 214 in order to lock connector 300 in place.

It is advantageous that a small rotation, 90 degrees or less for example, is required in order to secure the capsule 300 in this embodiment, in the manner of a fluid and gas tight quick-lock connection. As illustrated, in accordance with the disclosure, two fingers 320 are provided on circumferentially opposed positions, each engageble with one of two provided gaps 218 and edges 216. While an edge 216 and gap 218 are illustrated, it should be understood that locking means may advantageously include, in accordance with the disclosure, providing on the opening end 214 an extension of any known or hereinafter developed type, including as examples circumferential rings, barbs, expanding elements, pivotable elements, cammed elements, tapered threads, self tapping threads, and machine threads. Thus, a twist-lock secures capsule 200 onto connector 300, and threads engage a storage cap 230 onto capsule 200 when not in use. In another embodiment, connector 300 and capsule 200 are unitary, and are not disconnectable.

Connector 300 is securable to hair iron 100 within compartment 150 by engaging cap tab 318 with a tab receiving lip 158. The tab 318 may be push-fitted, snapped, or slid into engagement with lip 158. In another embodiment, connector 300 is secured within compartment 150 by a releasable clip (not illustrated). Furthermore, some embodiments include no engagement means for securing connector 300 within compartment 150 beyond the cap's 300 and capsule's 200 frictional engagement with surface or walls of compartment 150 and the surface of cover 500. Additional means for securing connector 300 to hair iron 100 are contemplated as being within the disclosure, including the use of connectors, fasteners, adhesive agents such as glue, or hook and loop fasteners.

Further provided, in accordance with the disclosure, is a pumping system for transferring liquid 400 from connector 300 and container 200 through and out of arm 102, to be applied to the hair of a user or subject. In one embodiment, fluid 400 stored within reservoir 212 is forced or expelled under pressure through tube 310 and out nozzle 314 of the cap. Nozzle 314 is connected to a dispensing channel or tube 162, and then to fluid dispensing ports 126 disposed proximate or between heating elements 106B, 106C. In this manner, fluid dispensingd can be heated, or heated sufficiently to produce steam, before being released. Dispenser nozzle 314 is insertable into a compartment 150 output nozzle connector 160, thereby in fluid communication with dispensing tube 162. Thus, by inserting the nozzle 314 into the compartment side opening 160, tube 310 is placed into fluid communication with dispensing tube 162. It is advantageous that output nozzle 314 fits in a water tight manner into output nozzle connector 160, thereby reducing lost fluid and reducing damage and cleaning requirements with respect to compartment 150.

Extending between heating elements 106B, 106C on upper arm 102 is at least one fluid dispensing hole or fluid dispensing port 126. In an advantageous embodiment, at least four (4) fluid dispensing ports 126 are positioned approximately equidistant from one another and linearly aligned the longitudinal center of heating plate 106, or if separate plates 106B, 106C are provided, advantageously between plates 106B, 106C, thereby providing optimal fluid 400 coverage to the hair of a user when hair iron 100 is in use. The diameter size of ports 126, and the number of ports 126, are configured in consideration of the amount of fluid 400 desired to be dispensingd, the viscosity of the fluid, and the desired velocity of the fluid 400, or steam, when dispensed. In another embodiment, in accordance with the disclosure, at least one dispensing port 126 is positioned on an alternative area of the inner or heating element side of arm 102 in fluid communication with dispensing tube 162, and to container 200 and pump chamber 312 and associated elements as described above, disposed within an opposite arm 104. It is also contemplated within the disclosure to position at least one port 126 on an outer side, particularly in an embodiment of the disclosure where arms 102, 104 are cylindrical, such as arms typically found on curling irons.

It is advantageous that port 126 is placed within proximity, between, or directly through, heating element 106 thereby heating fluid 400 as it is dispensed. The heating element 106 may be set to a sufficiently high temperature to advantageously dispense fluid 400 as a gas, such as steam for example. In another embodiment, an additional heating element (not illustrated) is provided within or proximate to compartment 150, capsule 200, pumping connector 300, or dispensing tube 162, to thereby heat fluid 400 prior to fluid 400 passing through output ports 126, thereby facilitating the production of hot gas, or steam for example, to the hair during use. However, a fluid 400 can be delivered in accordance with the disclosure without being heated, such as when the heating element proximate to the arm opening 126 is turned off, or when ports 126 are positioned away from element 106. In another embodiment, fluid may selectively be heated, for example by shutting off heating elements 106B, 106C, or dispensing fluid away from heating elements 106, 106B, 106C, for example using a valve switch (not shown) to an alternate set of output ports 126.

Fluid 400 is transferable from reservoir 212, through cap chamber 312, through dispensing tube 162, and out opening 126, for example under pressure, to thereby pass onto the hair of a user or grooming subject, as hair iron 100 is passed over the subject's hair. In one embodiment, fluid 400 is pressurized by a push pump 164, provided on an exterior surface of iron 100, for example upon the heating element side of at least one of arm 102 or 104. Pump 164 is fluid communicable with dispensing tube 162, and can include an elastically deformable material, such as rubber, whereby when pump 164 is pressed inwards or compressed, the pumping system is pressurized and fluid 400 is pressurized to pass out of openings 126. When pressure to a compressed pump 164 is removed, such as when a user ceases to press pump 164, the pump automatically returns to its rest position. In the embodiment illustrated, pump 164 is in fluid communication with chamber 312, and includes a pressing element 164A attached to an internal spring 168 for returning the pressing element to its resting state. Pressing element 164A may be pressed by a protruding element on an opposing side of iron 100, for example pump block 166, or by a finger of an operator.

With reference to FIGS. 13-14, an operation of a pumping system 190 of the disclosure may be seen in diagrammatic form. As pump pressing element 164A is depressed, air is forced into pressurizing tube 192 at port “C”, where it passes into connector 300 at port “B”. Pressurized gas is admitted into capsule reservoir 212 through collar 194, which admits air into reservoir 212, but prevents fluid from leaking from reservoir 212 by forming a liquid tight seal therewith. Pressure, and fluid, is prevented from being released through port “B” by a one way valve 316. As gas pressure within reservoir 212 is raised, fluid 400 is forced into reservoir tube 310, out through port “A”, and into dispensing tube 162, to be dispensed through dispensing ports 126. When pressing element 164A is released, air is drawn into pump 164 through inlet “D”, through a one way valve 196, and a pumping cycle may then be repeated.

With reference to FIGS. 1A, 1B, in one embodiment, a pump block 166 is provided on lower arm 104, positionable to interfere with pressing element 164A of pump 164 when arms 102, 104 are closed, to thereby activate pump 164 each time arms 102, 104 are closed after having been opened or apart. Pump block 166 may be moved from a lowered or stored position, shown in FIG. 1A, to a raised or engageable position shown in FIG. 1B, by moving pump block switch 118, or other mechanical means, positioned within arm 104, to urge pump block upwards and toward an opposite arm. When pump block 164 is in a raised position, pump block 164 can be pressed against pump 162 when arms 102, 104 are closed and, as a result, fluid 400 is pressurized and released from ports 126 with each squeeze or closing of arms 102, 104. When pump block 164 is in a lowered position, pump 162 and block 164 do not interact and, consequently, no fluid 400 is released by closing arms 102, 104. In an alternative, pump 164 may be raised or lowered to engage pump block 166, or some other opposing structure, when arms 102 and 104 are hinged towards each other. In the embodiment shown, a ramp 118A slidingly engages a bottom surface of pump block 166 to move pump block 166 upwards, or to release pump block 166 to move downwards, with respect to an inside surface of an arm opposite pump 164. Biasing means 118B can be provided to ensure movement of pump block 166 to an opposite position than is urged by movement of switch 118, or switch 118 may positively engage and move pump block 166.

As illustrated in FIGS. 3 and 4, when capsule 200 is disengaged from pumping connector 300, a storage cap 230 is provided in order to seal capsule 200 when stored or not in use. In one embodiment, at least a portion of storage cap 230 is internally threaded in order to engage a lower thread 222 provided proximately farther from opening 214 than upper thread 216. In securing storage cap 230, the internal threading of the storage cap 230 slides over the opening 214, passing upper thread 216, then engaging with lower thread 216. In another embodiment, storage cap 230 and pumping connector 300 are securable to capsule 200 by the same or similar means. For example, in one embodiment, fingers 320 are internally provided in storage cap 230, thereby permitting storage cap 230 to engage the locking means in similar manner as pumping connector 300. In another embodiment, storage cap 230 is engagable with upper thread 216 in similar means as described above in reference to the engagement between capsule 200 and connector 300.

In an advantageous embodiment, hair iron 100 includes means for regulating the pumping system or controlling the output of fluid or product 400. Advantageously included is a fluid switch or control 118, illustrated as being provided on arm 104, but may also be provided on arm 102 in another embodiment. In one embodiment, switch 118 operates in a binary, on or off, manner thereby permitting or restricting engagement between block 166 and pump 164, depending on whether a user prefers using iron 100 with or without fluid 400 being automatically applied upon closing or squeezing arms 102, 104 together. Intermediate stops, for example additional ramps 118A, can be provided to establish a range of fluid output for each press of pump 164. An additional means for regulating the output of fluid 400 is through adjustment of the opening of a nozzle, for example nozzle 314, or output ports 126. Adjustment of the nozzle opening may be carried out manually by a user's manipulation of an integrally provided cover or sealing element provided on arm 102. Adjustment of nozzle 314 may also be accomplished by sealing the nozzle 314 at the pump connector 300 side, where the connector 300 is provided with means for restricting fluid 400 from traversing through nozzle 314. Methods of controlling fluid 400 output are in addition to operating the iron 100 with connector 300 and/or capsule 200 removed from the iron during use. So as to permit the connector 300 and capsule 200 to be removed during use of iron 100, it is advantageous that an embodiment of the disclosure features no exposed electrical components within compartment 150.

It should be understood that the present disclosure is not limited to substantially straight arms 102, 104 with substantially planar heating elements 106. An embodiment of the disclosure includes a hair iron 100 comprising non-planar or curved heating elements 106, to form curling irons or curling tongs of the disclosure. In one embodiment, a capsule 200 and pump connector 300 are disposed within a compartment 150 provided in a portion of a curling iron.

In accordance with the disclosure, fluid 400 may be comprised of any known, or to be developed, treatment or product depending on the specified needs of the user. It is advantageous that the disclosed disposable capsule system permits quick and easy replacement of capsule 200. For example, one capsule 200 containing a first fluid composition 400 may be switched for a different capsule 200 containing a different fluid composition 400, for example during the same or subsequent sessions, with the same or different hair being treated. In one embodiment, the fluid is comprised of combination of water and treatment such as argan oil, keratin, or collagen, a conditioner, a straightener, hair nutrients, a heat protecting agent, for example, or combinations of the above. This embodiment may approximately comprise 97% water and 3% treatment. Although materials may be combined in any ration which produces a beneficial substance which will flow through pumping system 190. In some concentrations, it may be necessary for material within capsule 200 to be heated before it may flow freely, for example heating using heating elements 106, 106B, 106C, or an additional heating element proximate capsule 200. In additional embodiments, capsule 200 and connector 300 are constructed in order to store, seal, and controllably release a gaseous compound within reservoir 212.

Components other than capsule 200 may also be readily disposable, such as connector 300. In one embodiment, for example, connector 300 is integrally connected to capsule 200, as opposed to the releasable engagement illustrated in the figures. In this embodiment, both connector 300 and capsule 200 are disposable and easily replaceable.

It should be understood that the term “disposable,” as used within the disclosure, is to be interpreted as describing a removable component which are not intended for multiple uses. This term is further characterized by the accompanying attributes of the described “disposable” elements. In some embodiments, for example, a disposable capsule 200 is composed of low cost material designed to decompose, degrade, or wear down after more than a single use, thereby making the capsule “disposable” after a single use. A disposable capsule 200 might, in another embodiment, feature a valve for one-way sealing opening 214, thereby permitting extraction of fluid 400, but not replacement of new or replacement fluid in the reservoir 210, thereby necessitating disposal of the capsule 200 after a single use. Disposable can additionally include properties which permit or foster rapid degradation in a land fill environment. Additional examples of how an element may be “disposable” should be apparent as described in the disclosure.

In addition to quickly and efficiently switching capsules 200 containing different types of fluid 400, it is advantageous that connector 300 and capsule 200 are both releasable from iron 100 so as to permit cleaning of hair iron 100. Various hair products 400 that may be used in conjunction with the embodiments of the disclosure, are known to be potentially corrosive and damaging to a hair iron, especially after repeated exposure over a period of time.

Hair iron 100 may be manufactured from plastics, polymers, ceramics, metals, composite materials, and any other known or to be developed material suitable for hair iron production, including plastic, metal, ceramic, and wood. In one embodiment, a frame 900 is fabricated from injection molded plastic with a coating, which can be a vacuum metalized coating, a spray painted coating, a film deposition or adhered layer, silkscreen, or other decorative coating having printed indicia or designs on one or more exterior surfaces. Electrical or electronic circuitry 202, suitable to power the iron 100 and heat heating elements 106 within the disclosed temperature range are further provided in accordance with the disclosure. In one embodiment, the circuitry is dual voltage capable to thereby be adaptable with a variety of electrical outlet voltages and frequencies. It is further contemplated as within the disclosure that far infared technology is provided in order to advantageously assist in hair styling methods.
